Fire Suppression systems are the first line of defense after a conveyor belt fire has started in an underground coal mine. Between 2000 and 2009, twentyfive fires in underground coal mines were caused by friction of conveyor belts against pulleys, drives, rollers, idlers, and bearings (MSHA). These fires were often not detected for

Challenge: This coal mine facility faced many challenges, as all bulk handling facilities do. Overcoming obstacles in improving the safety of their conveyor system was a top priority. These type of conveyor systems have a tendency to mistrack causing the belt to cut into the hanging metal brackets holding the return roller in place. If and when

Conveyor systems were first invented in the late 1800's (Product Handling Concepts, 2014). These systems were constructed using wood and leather. In 1905, the first mining related material handling systems was implemented in a coal mine.
